DETAILED DESCRIPTION

Reference will now be made to the drawings wherein like referencenumerals identify similar structural features or aspects of the subjectdisclosure. For purposes of explanation and illustration, and notlimitation, an illustrative view of an embodiment of a tray inaccordance with the disclosure is shown in FIG. 1A and is designatedgenerally by reference character 100.

Other embodiments and/or aspects of this disclosure are shown in FIGS.1B-7 . Certain embodiments described herein can be used to enableautomated stacking of trays whether misaligned or otherwise.

In accordance with at least one aspect of this disclosure, referring toFIGS. 1A-2B, a tray 100 can include a plurality of first medializationfeatures 101 located at a top portion (e.g., extending from a topmostsurface and/or edge) of the tray 100, and a plurality of secondmedialization features 103 disposed at a bottom portion (e.g., extendingfrom a bottom panel) of the tray 100. The first medialization features101 can be configured to interact with the second medialization features103 of an adjacent stacked tray 100 to cause medialization of theadjacent stacked tray 100. Medialization (e.g., centering to a midline)can cause tray alignment (e.g., of central axes of multiple trays 100)and automated stacking of trays 100. For example, the medializationfeatures 101, 103 can be configured to cause a center axis of a top trayto have a motion vector pointing at the center axis of a bottom traysuch that the center axes converge as the adjacent trays are verticallystacked.

In certain embodiments, the plurality of first medialization features101 can be or include post tabs 105 extending upwardly from and/orbeyond an uppermost portion of the tray 100. In certain embodiments, theplurality of second medialization features 103 can be or include one ormore folding tabs 107 defined in a bottom of the tray 100.

The folding tabs 107 can be configured to be pushed upwardly by the posttabs 105 (e.g., as shown in FIG. 1C). The folding tabs 107 and the posttabs 105 can be configured to interact to cause medialization ofadjacent stacked trays 100 during stacking. For example, with three ormore folding tabs 107 (e.g., four as shown, one in each corner of tray100) the forces generated by the post tabs 105 pushing up the foldingtabs 107 (e.g., due to the material resistance in folding and/or theweight of the folding tabs 107), successive trays 100 will tend tomedialize to center each tray 100 when stacked on an adjacent tray 100.

Each folding tab 107 can be connected to the base panel 109 at a tabfold line 111. In certain embodiments, the tab fold line 111 ispositioned such that the folding tabs 107 fold inwardly while foldingupwardly (e.g., as shown in FIG. 1C). The tab fold lines 111 can be anysuitable fold line (e.g., a single crease) and can be sized (e.g., alongwith a thickness of the material forming the tray 100) to provide apredetermined resistance in folding. In certain embodiments, the tabfold line 111 can be straight. In certain embodiments, the tab fold line111 can be curved (e.g., convex and/or concave). In certain embodiments,the tab fold line 111 can extend across or can be only a portion acrossthe base panel. The tab fold line 111 can be formed on an upward facingsurface of the base panel 109 such that the indentation is downward. Anysuitable crease type or other suitable fold line type is contemplatedherein.

The tray 100 can include a plurality of vertical posts 113. Eachvertical post 113 can include a respective post tab 105 extendingupwardly therefrom. In certain embodiments, each vertical post 113 caninclude an inner wall 115 and an outer wall 117 and each vertical post113 can define a cavity 119 between the inner wall 115 and outer wall117 such that a tray area 121 of the tray 100 is separated from thecavity 119 by the inner wall 115 of each vertical post 113.

In certain embodiments, each folding tab 107 is within a respectivecavity 119 (e.g., within a planform projection, e.g., as shown in FIG.1B) of each vertical post 113. In certain embodiments each post tab 105can be formed from each outer wall 117 of each vertical post 113.

As shown in FIGS. 1A-1C, each vertical post 113 can be located at acorner of the tray 100, for example. Each post tab 105 can also includea corner shape (e.g., bent with the corner as shown). In certainembodiments, each post tab 105 can also include a ramp shape (e.g., asshown in FIG. 1C). In certain embodiments, each vertical post 113 caninclude a tab aperture 123 defined at a bottom thereof to receive thepost tab 105 to allow the post tab 105 to nest within the tab aperture123 and/or to move outwardly and inwardly relative to the tab aperture123 (e.g., during medialization).

The tray 100 can be made of paper material or plastic in certainembodiments (e.g., cardboard as shown). Any suitable material iscontemplated herein.

In accordance with at least one aspect of this disclosure, referring toFIGS. 2A and 2B, a blank 200 can be configured to form a tray asdisclosed herein, e.g., a tray 100 as described above.
